CogVideo uye CogVideoX
CogVideo (2022) yaive yekutanga-yakakura yakavhurika mavara-kune-vhidhiyo modhi, uye CogVideoX (2024) ndiyo inonyanya kugona yakavhurika-sosi mutsivi kubva kuTsinghua/Zhipu AI.
Pfupiso
They matter because they put high-quality video generation into the hands of the open community, not just big corporate labs.
Kudzika Kwakadzika
CogVideo, yakaburitswa muna 2022, yakavakirwa paCogView2 text-to-image transformer uye yakashandisa multi-frame-rate, autoregressive maitiro kugadzira zvipfupi zvipfupi, ikava yekutanga kuburitswa pachena hombe-kune-vhidhiyo modhi uye inotsigira Chinese neChirungu zvinokurudzira. Mutsivi wayo wa2024, CogVideoX, igadziriso yakazara: inoshandisa 3D causal variational autoencoder kudzvanya vhidhiyo munzvimbo uye nguva, kozoti Nyanzvi Shandura ine chinangwa chekuparadzira icho chinopindirana pamusoro pezvinyorwa uye vhidhiyo tokeni zvakabatanidzwa pamwechete. CogVideoX modhi (muhukuru senge 2B uye 5B paramita) inogadzira masekonzi akati wandei ekubatana, vhidhiyo inofamba-pamusoro pazvisarudzo zvakaita se720x480 uye inotsigira mufananidzo-kune-vhidhiyo uye kuenderera kwevhidhiyo. Nehurombo, huremu uye kodhi zviri paruzhinji, zvichikuchidzira masaisai enharaunda yakanaka-tunes, maturusi, uye tsvagiridzo.
Technical Insight
CogVideoX's 3D causal VAE inokwenya vhidhiyo yakasvibira kuita compact latent vhoriyamu, ichicheka nhamba yetokeni kuitira kuti transformer ikwanise kutevedzera marefu akateedzana zvinokwanisika. Nyanzvi inoshandura inoshandisa adaptive layer yakajairwa uye inobatanidza zvinyorwa uye zviratidzo zvekuona kuitira kuti maitiro maviri aya aenderane kune mumwe nemumwe zvakananga, achivandudza mameseji-vhidhiyo kurongeka. Dzidzo inofambira mberi pakuwedzera zvigadziriso uye nguva, pamwe nekuchenjerera data zvinyorwa, zvinopa zvakapfava, zvakanyanya semantic kutendeka kufamba.
Strategic Impact
Kumhanya uye chiyero
Visual AI inogona kuita otomatiki yekuongorora, yekuona, uye yekumaka mabasa pachiyero.
Vaka sarudzo
Zvikwata zvekugadzira zvinogona prototype pfungwa nekukurumidza nekudzokororwa kwemaoko mashoma.
Team uye workflow
Mashandisirwo anogona kushandisa masaini emifananidzo nemavhidhiyo ayo aimbove akaoma kugadzirisa.
Ramangwana reCogVideo uye CogVideoX
Seimwe yemhando dzakasimba dzakavhurika dzevhidhiyo, CogVideoX inotsigira kukurumidza kukura ecosystem yezvakanaka-tunes, control adapter, uye yakareba-nguva yekuwedzera. Tarisira kuenderera mberi kunowanikwa mukureba kweclip, kugadzirisa, kufambisa kwechokwadi, uye kudzoreka, pamwe nekubatana kwakasimba nemufananidzo-kune-vhidhiyo uye editing workflows. Huremu hwayo hwakavhurika hunoreva kusaita purofiti, vaongorori, uye mastudio madiki anogona kuvakira pamuganhu-kirasi vhidhiyo chizvarwa pasina chevaridzi chekuchengetedza gedhi, ichimhanyisa zvese zvekugadzira uye chengetedzo-yakatarisana kuyedza.
Real-World Implementation
Kugadzira kapfupi kekurondedzera kubva kuChinese kana Chirungu chekukurumidza uchishandisa uremu hwakavhurika zvakazara
Kushandura imwe chete yakarodzwa mufananidzo kuita vhidhiyo inofamba kuburikidza neCogVideoX mufananidzo-kune-vhidhiyo
Kunyatsogadzirisa iyo yakavhurika modhi pane yakasarudzika maitiro kana hunhu hwe indie animation
Vatsvagiri vanomisikidza nzira nyowani dzevhidhiyo-zvinopesana neinodhirowa yakavhurika baseline
Njodzi & Guardrails
Kodzero dzemifananidzo uye kubvumirwa kunogona kuve njodzi dzepamutemo kana provenance isina kujeka.
Kuita kwemuenzaniso kunogona kusiyanisa kupenya, huwandu hwevanhu, uye nharaunda.
Manyepo enhema anogona kusacherechedzwa kunze kwekunge zvikumbaridzo zvekuvimba zvikatariswa.
Implementation Roadmap
Tsanangura maitiro ekugamuchirwa echokwadi, kurangarira, uye mutengo wekukanganisa.
Edzai nedata rinoenderana nemamiriro chaiwo ekugadzira.
Wedzera ongororo yemunhu kune yakaderera-kusavimbika kana yakakwirira-inokanganisa kufanotaura.
Tevera modhi kudonha uye simbisa mushure mekuchinja kwekamera kana dataset.

What is CogVideo and CogVideoX?
CogVideo (2022) yaive yekutanga-yakakura yakavhurika mavara-kune-vhidhiyo modhi, uye CogVideoX (2024) ndiyo inonyanya kugona yakavhurika-sosi mutsivi kubva kuTsinghua/Zhipu AI. Ivo vane basa nekuti vanoisa emhando yepamusoro vhidhiyo chizvarwa mumaoko enharaunda yakavhurika, kwete maLab makuru emakambani.
Chii chakakosha nezve CogVideo's 2022 kuburitswa?
